OTTO SCHUBERT, OF WATERLOO, IOWA; ALFRED SCI-IUBERT ADMINISTRATOR OF SAID OTTO SCHUBERT, DECEASED.

POWER-OPERATED PLOW.

Application filed March 25, 1915.

To all whom it may concern:

Be it known that I, OTTO SCHUBERT, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Power-Operated Plows, of which the following is a specification.

My invention relates to improvements in motor-operated plows, and the object of my improvement is to supply devices of this type with means for guiding the plow in a straight furrow, with mechanism for changing to make another like furrow beside it, said device being actuated by traction applied to a guiding cable connected transversely between adjustable anchoring-means at opposite ends of the furrows. This object I have efiected by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which a Figure 1 is an upper plan view of my improved power-operated plow and of portions of the cables and anchoring-means for same. Fig. 2 is a side elevation of. said device, showing parts broken away, or removed. Fig. 3 is a front elevation of my improved machine. Fig. 4 is a side elevation, on a larger scale, of one of the earth grappling hooks or anchors of said device. Fig. 5 is a plan diagram, showing the taut parallel guide-rods with their anchors and havlng a transverse cable connected therebetween with my improved power-actuated plow operatively engaged with said cable.

Similar numerals of reference denote corresponding parts throughout the several views.

In the drawings, the numeral 1 denotes a rectangular main frame supported on the pivoted axles 4 and 5, the'latter having carrying wheels 2 and 3 mounted thereon respectively.

The numeral 15 denotes a longitudinally arranged and movable structure or frame seated within said main frame and being a little longer than said main frame with like pairs of vertically spac'edrollers 24; and 25 mounted in the lower parts of the extremities of said structure. A shaft 12 is mounted transversely in bearings on the upper part of said frame and has a relatively large sprocket wheel 30 rotatably but non-slidably thereon and having one end of its hub pro- Specification of Letters Patent.

vided with a clutch face 31. A sleeve 32 is slidably non-rotatably mounted on said shaft and has a clutch face adapted to be mated with the clutch face 31. The sleeve 32 has an annular groove adapted to receive a fork on a bent arm 33 which has a downwardly-directed art 34 received into an eye 35 of a lever 3 extending longitudinally along one side of the structure 15. On the same side, said structure 15 has a rectangular open bracket 40 and which has converging downwardly sloped braces 39. The lever 37 lies across said braces and is pivoted on a rod 36 to a transverse partof the frame 1. Said lever may be operated by hand when desired to clutch or unclutch said parts. When the structure 15 is moved longitudinally to the left from its extreme position to the right shown in Fig. l, the lever is forced up on one of said braces 39 and rocked transversely in such a way that the arm 33 is caused to shift said clutch parts out of mesh with each other. The clutch parts remain uncoupled until the structure 15 has passed to the left-hand limit of its movement, when the lever 37 may be rocked back by hand when slightly slid up on said rod to engage said clutch parts together. The lever is acted upon by the other oblique brace 39 on the return movement of the structure 15 to disengage the clutch parts while such transfer is being made. A prime mover 61 is mounted in the frame 1, whose crank-shaft carries a sprocket-pinion 6O operatively connected to the sprocket-wheel 30 by a sprocket-chain 59. ()n the extremities of the shaft 12 without the frame 1, are mounted like sprocket wheels 13, and sprocket wheels 14: are mounted on the outer ends of the aXle 4 so that sprocket chains 65, as indicated by Fig. 1, may be operatively engaged about said sprocket wheels on each side of the machine when desired, to furnish forward traction to the machine by direct action of the prime mover therein. These chains may be left on said sprocket wheels when the plow is in use and additional forward traction is necessary, but under ordinary conditions are removed and used only for road traction purposes since other means are provided for ordinary traction of the machine while plowing.

The numeral 26 denotes a relatively large traction-wheel or concaved edged driving for said rods are best shown in Figs. 4 and y 1. The numeral 53 denotes a short section of plank laid flat on the ground and having a pair of parallel bars 55 and 56 secured thereto by means of clamping brackets 54. A plurality of curved anchors'57 are pivotally mounted on the bar 55 independently of each other, and each has ahandle 58 convenient for use When fixing the anchor in the ground or removing'it therefrom. Each anchor has a spadiform barb 64 which gives it a firm hold upon the soil when embedded in the ground. Each end of the rods or cables 50 and 66 is provided with a set'o'f these anchors secured thereto by means of pivoted ars '51 and a prop 52, the latter holding up the endof the cable a suitable distance from the ground surface. Said rods 50 and 66 are stretched as rigidly as possible between said anchors. Q11 each end of the transverse flexible cable 22 is secured a loop 23 formed on a solid transverse body or stop. The numeral 42 denotes a flexible bar or'rod bent medially to have its members crossed and. forms medial loop which is connected by means of a ring 41 to said loop 28. Thenumerals 24 and 25 denote vertically spaced idler rollers mounted in the .ends of the longitudinalmovable structure '15 with the cable 22 passed outwardlybetween them. The members-of the spring bar 42 have their middle parts connected by means of adjustably connected chain parts 43. Upon each rod and 66 is mounted a pair of like releasable grabs or clamps-arranged for alternate step'by step movements therealong. Said clamping means nearest one of said anchors at the starting point along the rod 50 eomprisesa pair of-oblong "plates 47 ,hingedtogether bymeans of pivotally connected straps 48 and 49 of which themiddle strap 49 only, extends beyond the amp, d is pivotally connectedto .the end" v of one of the members of the springrod 42.

thesaidirod when the Said plates are forced together. The other clamping means com- Grab points 67 extend from the opposed inner'longitudinal edges oftheplates 47 toward each other and opposite sides of the rod 50 andare adapted to securely engage prises like plates 44 hinged -,together by \like straps'45 and 46 of whichthe, longer. middle strap 46 is pivotally connected to the end of the other member of the spring rod 42. It will be observed that the inclinations of the straps in both said clamping means are the same, so that when the spring rod 42 is under tension, one pair of clamping means is free from the rod 50 while the other clamping means is secured thereto.

Referring now to Fig. 2, the numerals 20 and 21 denote oppositely directed plows located at the opposite ends of the machine, mounted on beams 19 and 18, respectively. The ends of said beams are pivotally mounted on horizontal fixed shafts 62 and are adjustable longitudinally thereon between pins 63 seated in certain of a plurality of open.- ings, not shown.

Referring to Fig. 1, the numeral 16 denotes a short cable passed over rollers on the frame 1 and having its ends connected to adjacent parts, of the plow-beam 18 and of the longitudinally movable structure 15, and so mounted therebetween that when said structure 15 is moved longitudinally in one direction, said connecting cable elevates the plow 21 and lowers said plow when said structure is moved in an opposite direction. A like cable is similarly connected between the plow 20 and the opposite end of the structure 15, whereby, when said structure is moved longitudinally, one plow is raised while the other is lowered. Said machine is made dirigible by the following means: Numerals 10 and 11 denote hand levers having the usual manually actuated detents adapted to be engaged with teeth on the rack sectors placed thereunder. The lower ends of said levers which extend below their fulcrums, are connected to medial parts of cables 8 and 9, respectively, and thecnds of said'cables are secured to opposite sides of \l-shaped hounds 6 and 7 secured to the medially pivoted axles 4 and 5,;rcspectively. By this means, either pair of carrying wheels 2 or 3 may be rocked laterally, while the other pair havetheir axlefixed.

Operation: Nhenthe clutch parts 31,.and 32 are engaged with each other and the motor started, the wheel 26 is rotated and the latter, by reason of=the grip which the opposed walls of the zigzag grooves 27 exerts upon the stretched cable 22, the wheeled frame 1 is pulled along-said cable until the transverse stop on the loop 23 engages the adjacentend of the longitudinallymovable structure 15. The pressure thereby exerted upon the members of the spring rod 42 spreads them apart as faraspermitted by the limiting chains 43 and while it pushes upon the strap 49 insuch a way as to pull the detentscf the plates 47 engaged with the cable 50, a pushis imparted to the other clamping means while yet in its freed condition which shoves the whole deviceastep farther along on said rod50. The pressure of said stop then reacts upon the longitudinally movable structure 15 by reason of the continued forward movement of the ma chine to push said structure back or toward the opposite end of the machine. In making this movement, the structure 15 pulls upon one cable 17 to lift the plow 20 out of the soil simultaneously slackening the other cable 16 to lower the other plow 21 into a working position. When the structure 15 moves back, one of its sloping bars 39 pushes over the lever part 38 to cause the arm 33 to separate the clutch parts 31 and 32, thereby stopping the rotation of the wheel 36 and the forward movement of the machine. The machine is placed in proper position to return 011 another furrow by using one of said hand levers to shift the appropriate pair of carrying wheels to allow the machine to ride to one side the space of the furrow and said wheels then return to their former position to move straight back to plow a parallel furrow. The engine is then reversed by means not shown and the hand lever 37 moved by hand to reengage the clutch parts 31 and 32. As the machine starts back, the spring rod members 42 are released from tension and move somewhat toward each other which causes the clamping members 44 to engage the rod 50 and free the other clamping members 47 while drawing them toward the first-mentioned clamping members the space of one furrow. In this manner, said sets of clamping members are moved along step by step on the rods 50 and 66 progressively to conform to the progress of the operation of the machine.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In combination, a frame mounted on carrying-wheels, a cable passed lengthwise through said frame, a wheel mounted rotatably in said frame, said cable being carried upon the circumference of said wheel and said wheel having means thereon for gripping the cable releasably as the wheel is rotated to roll thereon, and relatively rigid parallel spaced rods or cables stretched between anchors, the firstmentioned cable being arranged between the second-mentioned cables with its ends movably connected thereto.
